If God gave you a chance to choose your skin color, would you want white skin or yellow skin?
80% of the girls may say firmly: choose white skin! The whiter the better!
As the saying goes [one white covers all ugliness], women, ancient and modern, Chinese and foreign, have never stopped their steps in the pursuit of whitening.
Edo Japanese used rice flour to whiten their faces. There is a saying that “white skin can make up for a person’s seven defects”. For Japanese women, white skin is an indicator of personal charm and socio-economic status. You can see that Japanese geisha painted their faces so white that they know their pursuit of whitening.
In order to have fair skin, ancient women in our country applied lead powder to their faces every day. Their faces turned white and suffered from chronic poisoning.
In many African countries, people with dark skin color are also crazy about whitening, even if it does harm to their bodies. As a result, many African countries recently issued a ban on the use of products with the function of whitening skin color.
In order to whiten our brains, we have racked our brains, but in the end we either drew water with a sieve or ruined our faces with unreliable chemicals. Is how the scientific and effective whitening method?
Let’s look at the natural skin color first!
The color of human skin is determined by the participation of many pigments, the most important of which is melanin.
Melanin is synthesized by melanocytes and stored in melanosomes. Caucasians have white skin because the melanosomes in their skin are small in volume, small in content and concentrated in distribution.
In fact, melanocytes can already be found as early as 50 days in our mother’s belly. When we are 6 months old after birth, the natural skin color basically takes shape.
What do you think of natural skin color? The skin color of the inner thigh and the inner upper arm, which cannot be sunned at ordinary times, is close to our natural skin color.
Parents gave it, how can it still turn black?
However, although some people are born white enough, their carelessness the day after tomorrow still makes them black.
Melanin is affected by the environment and accelerates its formation.
Apart from systemic diseases, local trauma and inflammation, the most common initiator of blackening you is ultraviolet rays.
Under the irradiation of ultraviolet rays, tyrosinase activity will be enhanced. Tyrosine will eventually generate melanin molecules through multiple reactions under the action of tyrosinase. Melanin molecules will gather together and be stored in melanosomes.
Melanosomes are first stored in melanocytes. After exposure to the sun, melanosomes are released to the entire epidermis, so our skin will turn black.
Skin photoaging
Don’t just worry about short-term exposure. A small amount of ultraviolet rays for a long time will also age the skin and change the skin color and texture.
For example, the whole area is dark, yellow and uneven in skin color. Freckles, chloasma and even senile plaques may appear on both cheeks and around eyes.
In addition, ultraviolet rays can also induce the breakage and disintegration of collagen fibers and elastic fibers and inhibit the regeneration of collagen. It is manifested as skin relaxation, wrinkles, drooping, etc.
All these whitening methods have been tried, but they merge?
Food Supplement Can’t Whiten
No matter eating bird’s nest, lemonade, various vegetables and fruits, VC effervescent tablets, various health care products, or whitening pills with strong wind, they cannot effectively whiten the skin! It is true that improper choice or excessive eating can make you fat.
Milk can’t wash your face white.
Mending shape with shape is a very primitive way of thinking, just like eating walnuts does not nourish the brain, washing face with white milk, soya-bean milk and rice washing water cannot whiten the skin.
Cucumber, lemon and other kinds of melon and fruit slices cannot whiten the skin.
Fruit and vegetable patches can bring moisture to epidermal cells. Many people feel very comfortable after using them, causing the illusion of replenishing water. However, whitening or skin care are not recommended. Because in addition to bringing temporary moisture, there is no other great significance.
On the other hand, the nutrients in fruits and vegetables may bring burden to the skin, causing skin allergy, irritation and other problems.
Patch facial mask can’t whiten the skin either.
Do you feel white after applying the facial mask every time?
In fact, this is because the keratinocytes of the epidermis temporarily absorb water and expand after the facial mask is applied, thus increasing the glossiness of the skin, thus having the visual “whiter” effect, but this effect will disappear after the moisture on the skin surface volatilizes.
In addition, there are some illegal products added with hormones and heavy metals that can quickly whiten skin, but will cause no small damage to skin.
The previous methods were all wrong, so how should I whiten my skin?
Sun protection
If you want to prevent photoaging and prevent the further development of photoaging, the most important work is sun protection!
For daily sun protection, select SPF 15 ~ 30, PA +/PA + + sunscreen.
When ultraviolet rays are strong in summer, it is safer to choose SPF 30 +, PA + + +. U.S. Sunscreen needs to bear the Broad Spectrum logo.
Warm Tip: Sun protection should be supplemented in time, and physical sun protection measures should be taken at the same time. To use sunshade umbrellas, wide-brimmed sunshade hats, sunglasses, etc., and try to reduce going out during periods of strong ultraviolet rays to avoid exposure to ultraviolet rays.
Repair
For the photoaging and pigment change that have occurred, it is necessary to interfere with melanin from time to time with external force to block all pathways of melanin from the source:
Reduce the supply of raw materials
We can use antioxidants vitamin C and vitamin E to inhibit tyrosinase activity and reduce melanin synthesis.
Prevent melanosomes from transporting
The melanosomes are trapped in melanocytes by external components and cannot be released, transmitted or transported out. Nicotinamide is one component that plays such a role.
Accelerate the transportation of melanin and promote its excretion.
For melanin that has been produced and transported to the epidermis, one of the common methods of medical cosmetology-tartaric acid rejuvenation is to help melanin metabolize from the stratum corneum.
In addition, blasting melanosomes by photoelectric means such as laser and strong pulse light can also promote metabolism, thus improving color spots.
The principle of common whitening ingredients on the market also works from the following three stages:
- Inhibit tyrosinase activity and reduce melanin formation: vitamin E, vitamin C derivatives, resorcinol derivatives (377 or rucinol), arbutin, etc. cut off melanin transmission channels: nicotinamide exfoliates cutin, accelerates metabolism: fruit acid, salicylic acid, etc.
